Abstract: A system, especially an installation, having a vehicle which is maneuverable on a floor is described. The vehicle has an RFID reading device which is connected to an antenna SL, and when the antenna SL enters the coupling region of a floor-installed antenna connected to a stationary RFID transponder, especially an RFID tag, then data stored in the transponder are able to be read out by the reading device. One or more permanent magnet(s) is/are situated on the floor, in particular fixedly joined in the floor, and the vehicle includes a sensor for detecting the direction of the magnetic field.

Abstract: System for ascertaining the number of revolutions of a rotationally mounted shaft, and method for ascertaining the number of revolutions of a rotationally mounted shaft, a permanent magnet being connected to the shaft in a torsionally fixed manner, the signal voltage generated by a microgenerator situated in an operative connection with the permanent magnet being supplied to an energy buffer, especially via a rectifier to a capacitor, a memory device for storing the number of revolutions being supplied from the energy buffer, the signal voltage of the microgenerator in particular being supplied to a counting logic device, which is supplied from the energy buffer and is connected to the memory device for reading out the respective old numerical value of the revolutions and for storing the respective newly ascertained numerical value of the revolutions.
